Abstract

An apparatus and method for estimating the position of a mobile robot capable of reducing the time required to estimate the position is provided. The mobile robot position estimating apparatus includes a range data acquisition unit configured to acquire three-dimensional (3D) point cloud data, a storage unit configured to store a plurality of patches, each including points around a feature point which is extracted from previously acquired 3D point cloud data, and a position estimating unit configured to estimate the position of the mobile robot by tracking the plurality of patches from the acquired 3D point cloud data.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims the benefit under 35 U.S.C. §119(a) of Korean Patent Application No. 10-2010-0016812, filed on Feb. 24, 2010, the disclosure of which is incorporated by reference in its entirety for all purposes.BACKGROUND[0002]1. Field[0003]One or more embodiments relate to an apparatus and method for estimating a position of a mobile robot, and particularly, to an apparatus and method for estimating a position of a mobile robot, in which the mobile robot estimates its own position by use of a distance sensor.[0004]2. Description of the Related Art[0005]With the development of new technologies in optics and electronics, more cost effective and accurate laser scanning systems have been implemented. According to a laser scanning system, depth information of an object may be directly obtained, thereby simplifying range image analysis and providing a wide range of applications. The range image is formed of a set of three-dimensional ...
